Pub Package Explorer

Use this workflow to read package source code for Dart or Flutter, including packages not currently installed in the project.

Choose the Source Strategy

1. Prefer .dart_tool/package_config.json when the package is already in the project dependency graph.
2. Use dart pub unpack when the package is missing from package_config.json or when source needs inspection before adding the dependency.
3. Prefer the installed package path when both are available to match the project-resolved version.

Resolve a Package Source Path

1. Confirm the project contains .dart_tool/package_config.json.
2. Read the package entry from packages[] by name.
3. Extract:

• rootUri (package root, usually in pub cache)
• packageUri (usually lib/)

4. Build source path as rootUri + packageUri.
5. Convert file:// URI to a filesystem path before reading files.
